Horizontal cabling length limitations :: | 4/55
| Horizontal cabling length limits are based on cable length from the termination of the media at the horizontal cross-connect in the telecommunications room to the telecommunications outlet/connector in the work area. Requirements Maximum horizontal length shall be 90 m (295 ft), independent of media type. For each horizontal channel, the total length allowed for cords in the work area plus patch cords or jumpers plus equipment cables or cords in the telecommunications room shall not exceed 10 m (33 ft), unless a multi-user telecommunications outlet assembly is used. If a multi-user telecommunications outlet assembly (MUTOA) is used, the maximum horizontal distance of twisted-pair media shall be reduced in accordance with the open office cabling formula, C = (102-H) / 1.2, W = C-5. Recommendations The length of the cross-connect jumpers and patch cords in the cross-connect facilities, including horizontal cross-connects, jumpers, and patch cords that connect horizontal cabling with equipment or backbone cabling, should not exceed 5 m (16 ft) in length.
